1.In a hydrometer test , the results are as follows:Gs =2.60 , temperature of water=24c ,and R=43at 60 min after the start of sedimentation (see figure 2.24 ) . what is the diameter , D, of the smallest -size particles that have settled beyond the zone of measurement at that time(that is , t=60 min)?
2.If aerosol particles were considered to be extremely large gas molecules, what would the gram molecular weight of a gas of 1.0 micron diameter particles having a density of 1000 kg/cubic meter.
